single-tooth worm reducer
Abstract The study mainly focuses the large emerging market of the chair lift when the mass population ages. The design of our chair lift was based on the issue of the mass aging population, and our layout is a motor spurring the single-tooth worm reducer. After we had a preliminary understanding of the product’s specifications, we can not only design the product that best meet the needs but can also achieve our goal with the lowest expense under limited budget. Designing a product is hard to success without numerous of failures, we have been through countless dead ends to find the best parameters. Eventually, we came out with the design of a worm gear speed reducer mechanism with a spur gear as our transmission mechanism. With the aid of Fortran, we were able to minimize our mistakes of calculation and save huge amount of time of redesigning at the same time. After multiple calculations, we were able to achieve the required load capacity, while reducing the body size of the reducer and its transmission mechanism in less than a width of 200 mm. The worm circumferential force and rated circumferential force we also observed by us. The background knowledge implemented in this study were based on the expertise we learned in Mechanical Design, and with the help of extra programming. At the end of the lesson we learned that the materials needed during our project is a lot fewer than we had imagined.
